This Concept Map, created with IHMC CmapTools, has information related to: Energy Concept Map Mathematical Component, Energy includes Kinetic Energy, Kinetic Energy is calculated by 1/2 * Mass (kg) * Velocity (m/s) * velocity (m/s), Energy is ruled by the Law of Conservation of Energy Energy cannot be crated or destroyed., Mass (kg) * Gravitational Force (N) * Height (m) can be illustrated by an example A 60kg man standing at the edge of a 20m high cliff will have a potential energy of 60 * 10 * 20 = 12000 J, Power (W) * Time (s) can be illustrated by an example A 70W fan is turned on for 1 minute will consume an electrical energy of 70 * 60 = 4200 J, Energy includes Sound, Electrical Energy is calculated by Power (W) * Time (s), Assuming negligible air resistance, a ball at an initial height is dropped to fall freely onto the ground. When in mid-air, the energy conversion involved is initial P.E = P.E in mid-air + K.E in mid-air A mathematical example A 500g ball at an initial height of 20m is dropped to fall freely onto the ground. When it reaches a height of 5m, calculate the rate at which the ball is falling assuming negligible air resistance. initial P.E = P.E at 5m + K.E at 5m 0.5 * 10 * 20 = (0.5 * 10 * 5) + (0.5 * 0.5 * v * v) Therefore, v = 17.3 m/s, Energy includes Gravitational Potential Energy, Energy includes Heat, Energy includes Electrical Energy, Energy is always transferred from one form to another. can be illustrated with an Energy Conversion example Assuming negligible air resistance, a ball at an initial height is dropped to fall freely onto the ground. When in mid-air, the energy conversion involved is initial P.E = P.E in mid-air + K.E in mid-air, 1/2 * Mass (kg) * Velocity (m/s) * velocity (m/s) can be illustrated by an example A 60kg man running at a speed of 10 m/s will have a kinetic energy of 1/2 * 60 * 10 * 10 = 3000 J, Energy is measured in Joules (J), Energy cannot be crated or destroyed. can be illustrated with an Energy Conversion example Assuming negligible air resistance, a ball at an initial height is dropped to fall freely onto the ground. When in mid-air, the energy conversion involved is initial P.E = P.E in mid-air + K.E in mid-air, Gravitational Potential Energy is calculated by Mass (kg) * Gravitational Force (N) * Height (m), Energy is ruled by the Law of Conservation of Energy Energy is always transferred from one form to another.
